Download Subsurface-4.7.5-x86_64.AppImage, make it executablechmod +x Subsurface-4.7.5-x86_64.AppImage and then simply run this file.Linux: Ubuntu: Add ppa?/subsurface to your software sources; the .deb files in that PPA can also be installed on sufficiently current versions Debian and LinuxMint; see the Downloads page and use http://ppa.launchpad.net/subsurface/subsurface/ubuntu to get our latest release version.

NOTE: While these builds will show you our latest features and updates, they may also show you our latest bugs and could potentially be unstable. Please be aware of that when trying them out! Subsurface is generally careful to create backups of your data and to avoid ever losing any dive data. It still seems prudent to be extra-careful when testing these builds.
